Combining power and sensitivity. GDRX is an ultra sensitive multi-channel digital receiver and signal processor. Separate channels for weak and strong signals provide an extremely wide dynamic range, so all backscatters of meteorological interest can be displayed across the entire operating range of the radar. Hosting the signal processor on a high performance commercial PC equips GDRX with the necessary computing power to handle modern algorithms (e.g. adaptive clutter filtering), while the elimination of proprietary hardware means customers may benefit from easy upgrade and advancements in processor speed for years to come. GDRX is fitted with an additional digital receiver channel and the corresponding signal processing chain, which removes the need for expensive hardware alterations when it comes to dual polarization migration.

  • High sensitivity and excellent linearity over a wide dynamic range comparable to an 18 bit digitizer
  • Dual polarization ready
  • Great variety of IIR, DFT, adaptive and statistical clutter filters
  • Continuous burst sample monitoring of signal spectrum, power for phase correction and compensation of RF power variations
  • On-board waveform generator for coherent transmitter types supporting phase-coding, pulse compression and test signal injection
  • Multi trip recovery
  • I/Q record and replay
